Heroku buildpack google chrome

Use either of these options if you're using heroku-buildpack-google-chrome to help webdrivers find the install path to Google Chrome.

Option 1: Set the WD_CHROME_PATH environment variable to whatever $GOOGLE_CHROME_SHIM points to.

$ echo $GOOGLE_CHROME_SHIM
=> /app/.apt/usr/bin/google-chrome-stable

$ RAILS_ENV=test bundle exec rake webdrivers:chromedriver:update WD_CHROME_PATH=/app/.apt/usr/bin/google-chrome-stable

Option 2: Set Selenium::WebDriver::Chrome.path (in your code) to whatever $GOOGLE_CHROME_SHIM points to.

require 'webdrivers'

Selenium::WebDriver::Chrome.path = ENV.fetch('GOOGLE_CHROME_SHIM', nil)
driver = Selenium::WebDriver.for :chrome
